一个简易文本编辑器，自己学习的第一个编辑器程序，共享一下，可以学习一下。 <title>ubb</title> <font face=""> <table width="300" cellspacing="0" cellpadding="1" border="0" bgcolor="buttonface"> <tr> <td height="20px" width="18px" onclick='doAction("Bold")' onmousedown="DoDown(e_bold );" onmouseover="On_Mouseover(e_bold) ;" onmouseout="On_Mouseout(e_bold);"> <img align="absmiddle" id="e_bold" src="bold.gif" style="max-width:90%" height="18px" border="0" alt="一个的简易文本编辑器源码_javascript技巧" > </td> <td height="20px" width="18px" onclick='doAction("Italic")' onmousedown="DoDown(e_italic);" onmouseover="On_Mouseover(e_italic) ;" onmouseout="On_Mouseout(e_italic);"> <img align="absmiddle" id="e_italic" src="italic.gif" style="max-width:90%" style="max-width:90%" border="0/" alt="一个的简易文本编辑器源码_javascript技巧" > </td> <td width="264px"> </td> </tr> <tr> <td colspan="3"> <iframe id="Editor" name="Editor" border="0" scroll="no" width="300" height="200" style="margin:0px"></iframe> </td> </tr> </table> <script language="javascript"> //initialize the iframe function window.onload() { Editor.document.designMode = "On"; Editor.document.open() ; Editor.document.write("") ; Editor.document.close(); Editor.focus (); } function On_Mouseover(thisTD) { thisTD.style.borderLeft = "1px solid buttonhighlight" ; thisTD.style.borderRight = "1px solid buttonshadow"; thisTD.style.borderTop = "1px solid buttonhighlight"; thisTD.style.borderBottom = "1px solid buttonshadow"; } function On_Mouseout(thisTD) { thisTD.style.borderLeft = "" ; thisTD.style.borderRight = ""; thisTD.style.borderTop = ""; thisTD.style.borderBottom = ""; } function DoDown(thisTD) { thisTD.style .borderLeft = "1px solid buttonshadow"; thisTD.style .borderRight = "1px solid buttonhighlight"; thisTD.style .borderTop = "1px solid buttonshadow"; thisTD.style .borderBottom = "1px solid buttonhighlight"; thisTD.style .paddingTop = "2px"; thisTD.style .paddingLeft = "2px"; thisTD.style .paddingBottom = "0px"; thisTD.style .paddingRight = "0px"; } function doAction(str) { var m_objTextRange = Editor.document.selection.createRange(); m_objTextRange.execCommand(str) ; } </script> </font> [Ctrl+A 全选 注:如需引入外部Js需刷新才能执行]
